Help with my husband

I have baby fever y’all!!! My husband knows it but he absolutely does not want another child. We have the means to support another child. He says he wants to live life and we couldn’t do anything with another child ( like we do anything now we take a vacation once a year) but the thing is he goes back and forth saying he maybe wants another kid then he’s like hell no. Y’all what do I do? I know I will forever regret not giving my child a sibling.
